r_textureMode GL_LINEAR_MIPMAP_NEAREST set the rendering mode: in order from lowest quality (fastest) to highest quality (slowest), [type] options are: GL_NEAREST_MIPMAP_NEAREST, GL_LINEAR_MIPMAP_NEAREST, GL_NEAREST_MIPMAP_LINEAR, GL_LINEAR_MIPMAP_LINEAR. Think of the 1st two as low and high quality for hardware that supports bilinear filetering, and the 2nd two as low and high quality for hardware that supports trilinear filtering.
